Only urine is tested in a DOT test. The DOT test is a 5 panel EMIT screen with a 50 ng cutoff limit for THC. If the sample passes the EMIT, the test is finished right then. If a sample fails the EMIT, it then undergoes a confirmation GC/MS test.
DOT tests are NOT observed unless you had been accused of tampering.
